Offshore Oil Accounted For 30% Of Global Output In 2015

According to new data from the EIA, global offshore oil production (including lease condensate and hydrocarbon gas liquids) in 2015 was at the highest level since 2010, and accounted for nearly 30 percent of total global oil production. Offshore oil production increased in both 2014 and 2015, reversing consecutive annual declines from 2010 to 2013.

Production from onshore tight oil plays has increased at a higher rate over the past several years and accounts for a growing amount of total oil production.

Most offshore production is in shallow waters, which are cheaper and less technically challenging, but there has also been a move toward deep water projects. Exploratory drilling in deeper water is costlier and more complex for companies, but technology advancements and the exhaustion of shallower prospects have led companies to explore increasingly deeper waters, particularly in Brazil and in the Gulf of Mexico.

Saudi Arabia is the Largest Offshore Producer

A significant amount of global offshore production is concentrated in a few countries. In 2015, five countries provided 43 percent of total offshore oil production: Saudi Arabia, Brazil, Mexico, Norway, and the United States.

Saudi Arabia is the world’s largest offshore producer and has several large offshore oil fields including the Safaniya oil field, which produces between 1.1 and 1.5 million barrels per day and is the highest-producing offshore field in the world. Saudi Arabia is responsible for 13 percent of the world’s total offshore production.

Brazilian offshore production grew by 58 percent between 2005 and 2015, making Brazil the second-largest offshore producer in 2015. This growth was driven predominately by the expansion of deepwater pre-salt projects, which should support small production increases in 2016 and 2017.

Mexico is currently the third-largest offshore producer and has seen increasingly smaller yields from offshore assets, with production falling by 31 percent from 2005 to 2015. The country still produced nearly 2 million barrels per day in 2015, accounting for 7 percent of global offshore production.

Norwegian offshore production declined 28 percent between 2005 and 2010 but has remained steady since 2010, with 7 percent of global offshore production originating from Norwegian fields. Norwegian output is forecast to rise slightly in 2016 and fall slightly in 2017.

United States offshore production has been boosted by recent strong production in the Gulf of Mexico. Between 2005 and 2015, total offshore production grew by 6.5 percent. With several large projects coming online in 2016 and 2017, the Gulf of Mexico is expected to see production climb by about 0.1 million barrels per day in 2016 and by an additional 0.2 million barrels per day in 2017. In contrast, U.S. onshore production is expected to fall by 0.8 million barrels per day in 2016 and by an additional 0.3 million barrels per day in 2017.
